So far decent results with SAS, though I have not received any checks yet. I not real happy with their payment information and giving much detail on that part.

The problem I keep running into is when Advertisers run out of money and their links go "down" and are useless. Seems the advertisers need to be on auto-deposit to prevent that from happening and a lot of them aren't.

A couple of advertisers I have run into aren't tracking properly either.

Have no problems with them, pay on time with consolidated payments. The only problem i've ever had was with merchants going temp offline, which isn't a problem anymore since I now work only with merchants on auto deposit.
